PURPOSE High fluid intake has been associated with a decreased risk of bladder cancer development in men. We evaluated whether higher fluid intake can impact tumor recurrence rates in patients with superficial bladder cancer. MATERIALS AND METHODS We conducted a prospective single institution analysis of fluid intake in 267 consecutive patients with superficial bladder cancer undergoing routi...

The purpose of this study was to examine if anticipatory sweating occurs prior to fluid consumption in dehydrated subjects. It was hypothesized that there would first be an anticipatory response to the sight of water, and then with drinking, a second response caused by mechanical stimulation of oropharyngeal nerves. Dehydrated subjects (n=19) sat in a heat chamber for 30 minutes. At minute 15, ...

An ultra-performance liquid chromatography-tandem mass spectrometry method has been developed and validated for the determination of ethylglucuronide (EtG) in oral fluid. Sample clean-up was achieved by solid-phase extraction with a Hyper-SEP SAX column. Negative ionization was performed in the multiple reaction monitoring mode. Two transitions were monitored for the analyte and one for the int...

Forty patients with moderate degrees of dehydration and acidosis because of acute watery diarrhoea were successfully treated randomly with either WHO recommended oral rehydration solution containing 2.5 g sodium bicarbonate or an oral solution containing 2.94 g sodium citrate in place of sodium bicarbonate per litre of oral rehydration rehydration solution. Efficacies were compared by measuring...

BACKGROUND Patients approaching death often have a decreasing oral intake, which can be distressing for relatives. Little is known about the relatives' experiences with and perceptions of oral intake at the end of life. AIM This study aims to contribute to a more thorough understanding of relatives' concerns regarding decreased oral intake of the patient at the end of life. DESIGN Qualitati...

Introduction: Water, as one of the most essential nutrients, is involved in almost all biochemical processes of the human body. Although different degrees of dehydration have various symptoms such as physical and mental decline, severe dehydration is associated with decreased survival capacity in the physiological environment of the body that can put individuals, especially the elderly, at the ...

BACKGROUND The use of alcohol and drugs may affect workplace safety and productivity. Little is known about the magnitude of this problem in Norway. METHODS Employee recruitment methods with or without individual follow-up were compared. The employees filled in a questionnaire and provided a sample of oral fluid. Samples were analysed for alcohol, ethyl glucuronide (EtG; a biological marker o...

The epithelial sodium channel (ENaC) plays critical roles in maintaining fluid and electrolyte homeostasis and is located in the aldosterone-sensitive distal nephron (ASDN). We previously found that Nedd4-2 C2 knockout (KO) mice showed salt-sensitive hypertension with paradoxically enhanced ENaC gene expression in ASDN under high oral salt intake. Eplerenone (EPL), a selective aldosterone block...
